- * (Suggestion: First read the macro, then read this explanation.

- *

- * Either generate the next value to OR in to a pixel or break out of this

- * while loop 

- *

- * This macro is used when we're trying to generate all 2^n combinations of

- * bits in mask.  What we're doing here is counting in binary, except that

- * the bits we use to count may not be contiguous.  This macro will be

- * called 2^n times, returning a different value in bits each time. Then

- * it will cause us to break out of a surrounding loop. (It will always be

- * called from within a while loop.)

- * On call: mask is the value we want to find all the combinations for

- * base has 1 bit set where the least significant bit of mask is set

- *

- * For example,if mask is 01010, base should be 0010 and we count like this:

- * 00010 (see this isn't so hard), 

- *     then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so

- *      we add that to bits getting (0100 + 0100) =

- * 01000 for our next value.

- *      then we add 0010 to get 

- * 01010 and we're done (easy as 1, 2, 3)

+ *
+ * This macro is used when we're trying to generate all 2^n combinations of

+ * the bits we use to count may not be contiguous.  This macro will be
+ * called 2^n times, returning a different value in bits each time. Then
+ * it will cause us to break out of a surrounding loop. (It will always be
+ * called from within a while loop.)
+ * On call: mask is the value we want to find all the combinations for
+ * base has 1 bit set where the least significant bit of mask is set
+ *
+ * For example,if mask is 01010, base should be 0010 and we count like this:
+ * 00010 (see this isn't so hard), 
+ *     then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so
+ *      we add that to bits getting (0100 + 0100) =
+ * 01000 for our next value.
+ *      then we add 0010 to get 
+ * 01010 and we're done (easy as 1, 2, 3)

- * ChangeGC/ChangeGCXIDs:

- * NullClient for the client since any access checking should have

- * already been done at a higher level.

- * 

- * If you have any XIDs, you must use ChangeGCXIDs:

- * use ChangeGC:

- *     v[1].ptr = pPixmap;

- *     ChangeGC(client, pGC, GCFillStyle|GCTile, v);

- * If you have neither XIDs nor pointers, you can use either function,
